MEASUREMENT AND ANALYSIS OF HARMONIC PRODUCED BY THE AUXILIARY POWER SUPPLY EQUIPMENT FOR RAILWAY VEHICLE

초록

It is essential to evaluate the harmonic characteristics of high-speed train using power electronics equipment such as converter-driven motor drives, battery chargers and auxiliary power supplies. The purpose of this study is to measure and analyze the harmonic characteristics of a Korea High-Speed Train(KHST) prototype. This paper presents the result of harmonics measurement and the analysis of harmonic characteristics in terms of loading, speed and operation mode.
